specification, and to the figures and letters of reference marked thereon.

My invention has for its object to improve the construction of separators for warp-beaming machines; and it consists in a certain im- [5 proved construction, which I will now pro ceed to describe.

The yarn as it comes from the reels to be applied to the loom-beam is passed first between a series of pins, so as to divide itinto a number of strands, then through a wire riddle, dividing it into strands of about sixteen threads, then through a separator formed of a zinc or copper plate provided with from one to three thousand holes or perforations, (one for each thread,) then through a comparatively coarse neck, and onto the loom-beam, which is secured in bearings and rotated by suitable mechanism. The yarn as it is separated covers a large area, and the threads being under tension draw toward the center and tend to cut or wear the lower sides of those perforations above the center and the upper sides of those below the center, while several rows at the center are scarcely worn at all.

3 5 As the perforations are thus worn sharp edges and corners are formed, upon whichthe threads are cut and broken, thereby delaying the operation of beaming and necessitating the removal and replacing of the separator by a new 0 one. These plates form a considerable item of expense in a large mill, and it is therefore the object of my invention to provide an improved separator in which the wearing-surfaces of the perforations are movable and re 5 movable, and can be changed when slightly worn,thus prolonging the life of the separator.

In the drawings, Figure 1 is a front, Fig. 3

' a side, and Fig. 2 a rear,view of a portion of a separator constructed in accordance with my invention. 7

Similar letters of reference in the several figures indicate the same parts.

The letter A indicates a portion of a separator having a number of perforations, a, corresponding to the number of threads in the warp. Now, as the threads B come to this separator they run from a number of independent strands on one side to a broad sheet, so to speak, of threads on the side next the beam, and are drawn over the lower edges of the upper series of perforations, 0, straight, or nearly so, through the central series, D, and over the upper edges of the lower series, E.

On the rearsido ofthe plate A,I place a number of removable horizontal iron or steel wires, 6 F, extending from side to side and held in position by means of wire loops f, soldered or otherwise secured to the back of the plate, as shown. These horizontal wires are about on a level with the lower sides of the perforations of the upper series, 0, and the upper sides of the lower series, E, or, in other words, on the wearing sides, so that the threads will pass over them and thus take all the wear off the sides of the perforations.

As the wires become worn by the threads they can be turned partly orwholly around or moved longitudinally, so as to present a new surface, and when badly worn can be re moved and new ones put in their places.

It will be observed that by employing my invention a single separator can be made to last for years, the wires being turned from time to time or replaced by new ones when necessary and at very little cost. 8 5

I claim as my in vention- 1. The'combinatiomwith the perforated sep aratingplate, of the transverse rods or wires forming the bearing-surfaces for one or more perforations in the plate, said wires being sup- 0 ported at one or more points between the end supports, substantially as described.

2. The combination, with the perforated separating-plate, of the transverse rods or wires forming the bearing-surfaces for one or more 5 perforations supported at one or more points intermediate the end supports, the wires above the center of the plate being located at the lower sides of the perforations, and those below the center being located at the upper IOO sides of the perforations, substantially as deg scribed.

3. The combination, with the perforated plate, of the rods or wires loosely supported 5 at three or more points in their lengths, and

forming the wearing-surfaces for one or more perforations in the plates, substantially as described.
